Which type of mirror generally used for face looking ?

A plane mirror is a flat, smooth mirror that reflects light in a way that the image looks upright, virtual, and of the same size as the actual object. This makes it perfect for daily activities like grooming, shaving, or applying makeup, because you see an exact likeness of your face.

Unlike concave mirrors, which can magnify or invert the image, or convex mirrors, which make objects look smaller, a plane mirror gives a true-to-life reflection, making it the most convenient for personal use.

In short, plane mirrors are commonly used for face-looking because they produce a clear, upright, and life-sized image.
